'1 h 07 m, it, may concern:

Be it known that I, \VILLIAM I. T1103? son, a citizen of the UnitedStates, residing in Newark, county of Essex, and State of X' ewJersey,have invented new and useful Im'provenrents in DynamoDriving, of

.which'the following is a description.

I l l I l l l l Y My invention has for its object to prol driving adynamo 01' generator by power derived from the motion of l a car axleand has for its principal object l to provide means whereby a dynamo maybe carried in operative position with respect to one of the axles oi. acar and so coni nected thereto as be driven thereby. i

In the drawing Figure I represents an I end view of a car truck carryinga dynamo, dynamo suspending mechanism and driving means comprehending myinvention. t Fig. it shows a longitudinal section of a f truck tl'iroughthe line AB of Fig. I and a side elevation of the dynamo suspensionrigging.

in the drawing, referring to both Figs. 1 I and H, 1 represents a carwheel provided with the usual axle 2 forming part l of the usual cartruck provided with thet end-sill and the usual safety sills lrepresentsa flanged driving pulley securely clamped upon the car axle so as torevolve therewith. Upon the upper side of the safety sills 5 there arebolted the two members 6 asby means of bolts 7, said members (3 beingprovided with up-turned extension ends 8 which are bolted to thetransverse angle-iron 9. The bolts 7 also carry the members 10 and 11which are firmly held thereby against the lower side of the safety sillsThe members 10 are so shaped as to bear against the under sides of themembers (i and both members 6 and 10 have registering slots cut thereinas indicated in dotted lines by the numeral 12. The members llare soshaped as to hang below the members 10 in such. manner as to, form asuitable space between said mem hers and are provided at theirextremities with slots indicated in dotted lines at 13. The members orblocks having cylindrical indentations therein as indicated at 1 1 serveto hold the transverse cylindrical bar 15 in place in its propervertical alinement by means of liners l6 placed between the mem-i bersand the members 10 and 11. Bolts i i i l I 17 passing through the slots12, liners 16, members 14, rod 15, members 14, liners l6 and slot 13serve to clamp the said members firmly in place and allow someadjustment by moving the bolts 17 in the slots 12 and 13. The bar 15passes through the lugs 18 of the generator 19 in such manner as tosupport the generator and allow the same to have a rocking motion uponthe rod 15 while the lateral position or the generator with respect tothe rod 15 may be determined by the spacing members 27 which may bepieces of pipe slipped upon the rod. The generator 19 is provided withthe driving pulley 20 engaging the belt 21 which also engages the pulley4: upon the axle. The dynamo is also provided with a lug 22 engaging theclevis 23 carrying the rod which passes through an opening in theangle-iron 9 and carries over the same the compression spring 25,against which is drawn the hand nut 26 threaded upon the rod 24. Theother side of the generator is provided with a lug 28 to which isattached the chain 29 which is made fastto the endsill in such manner asto prevent the genera'tor from swinging too far in a direction away fromthe axle.

It the members (i, 10 and 11 be properly fastened in place upon thetruck as by the bolts 7 and the generator be placed upon the rod 15 andproper spacing members 27 placed upon the rod and its ends placed inmembers let, the generator by proper selection of liners 16 may be giventhe proper vertical position for operation, then by movement of thebolts 17 in the slots 12 and 13 the generator may be given the properhorizontal position for operation, then if the nuts be brought up uponthe bolts 17 the generator will be held in proper operative relation tothe axle 2, then if the pulley 4 be properly alined with reference tothe generator and secured to the axle 2 the belt 21 may be readilypassed around the driving pulley 4 and the dynamo pulley 20. This may becut and spliced to the proper length and mi be brought to, the propertension by screwing rip of the hand nut 26 which will tend to compressthe spring so as to cause the rod 2ft to tend to draw the generator 19and pulley 20 away from the car axle 2.

It will be obvious that my invention protrate one form of dynamo drivingcomprevides a simplefstrongand durable, as well I as adjustable, frameor support for carrying the generator in such position that the drivingbelt may be passed over the end-sill of the truck and that the drivingbelt will be held taut and at roper tension regardless of ordinary play0 the truck frame u on its springs and throughout the ordinary ateralmolvement of the car axle within its journa s.

I do not wish in any way to limit myself to the exact form or details ofconstruction shown in the attached drawing used to illushending myinvention as it is obvious that considerable departure may be madetherein and still within the scope of my invention which is as set forthin the following claims to wit:

1. The combination with a car truck having an axle, an end-sill andsafety sills, of a dynamo and means for carrying the dynamo .upon saidtruck in operative relation to said axle comprehending members attachedto the upper side of the safety sills, members attached to the lowerside of the said safety sills, a transverse member supported between themembers carried by the safety sills on each side of the truck and meansfor mounting the dynamo upon said transverse member below the armature.

2. The combination with a car truck having an axle, an end-sill andlongitudinal sills, of a pulley mounted to revolve with said axle, adynamo, a transverse member placed below the center thereof andsupporting said dynamo and members supported both by the end-sill andthe longitudinal sills of said truck carrying said transverse member, adriving pulley for said dynamo, a belt engaging the said dynamo drivingpulley and the pulley upon the axle and means tending to revolve saidgenerator upon said transverse member to preserve substantially constanttension upon said belt.

3. The combination with a car truck comprising longitudinal sills, atransverse sill and an axle, of a.pulley mounted upon said axle, adynamo support attached .to a plurality of the longitudinal sills and toone of the end-sills and provided with a transverse member, a dynamomounted upon said transverse member in a position above the same, adriving pulley carried by the said dynamo, a driving belt inclosing thepulley upon the axle, the end-sill and the dynamo pulley and means forpreserving substantially uniform tension upon said belt.

4. The combination with a car truck having an axle, a pulley upon saidaxle, a transverse sill and longitudinal sills, of longitudinalsupporting members carried by a plurality of the longitudinal sills andthe endsill, a transverse member carried thereby, a dynamo carried uponsaid member and rest ing thereon at a point below its center, a pulleyupon said dynamo, a second transverse member carried by the saidlongitudinal members, a belt engaging the pulley upon the axle and thedynamo pulley and means carried by the said last named transverse memberfor causing substantially uniform tension upon said belt.

5. The combination with a car truck having an axle, apulley upon saidaxle, a plurality of longitudinal sills and an end-sill, of memberscarried by a longitudinal sill on eachside of the truck and an end-sill,a transverse member adjustably secured between said longitudinalmembers, a dynamo supported upon said transverse member at a point belowits center and capable of rotary motion upon said member, a drivingpulley carried by the said dynamo, a belt inclosing the end-sill andengaging the pulley upon the axle and the dynamo pulley in such mannerthat rocking the generator upon its transverse supportin member variesthe tension upon said belt and yielding means tendingto revolve thegenerator upon said transverse member in a direction away from the caraxle.

6. The combination with a car truck having an axle and longitudinalsills, of means for carrying a dynamo upon said truck comprehending amember upon each side of the truck carried upon the top of alongitudinal $111, a member carried against the lower side of alongitudinal sill, a member fora portion of its length held against saidlast named member below the longitudinal sill,

between the extremity thereof and the two above named members, atransverse member passing through said opening and means whereby saidtransverse member may be positively clamped in position in said openingbetween the members.
